Gentlemen, one and all: just a comment regarding an apparently bygone era when things were simpler. It used to be the case back when rear hubs were 120mm - 126mm, BB's were asymmetrical. That is, there was about another 5mm or so of spindle on the drive side vs. the non-drive. This difference made it much easier to match a crankset up with the freewheel to get a good chainline. And that spacing maintained a good low Q-factor! Then along came the 130mm - 135mm era where the rear dropouts were spread wide enough to accommodate 9 - 11 speed cassettes and the BB's became symmetrical to accommodate the wider chain stays (which in the case of MTB's seemed irrelevant since the crank arms were curved outward to provide for a wider "Q-factor" on purpose) and still provide wide enough crank arm clearance on either side of the frame. So, all of this is simply to say that in this day and age one is going to run into this kind of problem over and over again unless the crankset manf. specifically recommends a BB spindle width for a specific rear dropout width. And it's all across the board!! I have a Surly 1x1, which comes with a 173mm BB shell and a defacto 135mm rear dropout width (since it's classified as a MTB) that required 1.5mm of spacers on the drive side of the BB just to get the single speed chainline even halfway straight and to get the pedals more or less equal distance from their associated L & R chain stays.
